Sony Reveals Launch Window for Dolby Vision 4K TV Update

According to a report by Forbes, Sony has announced a Dolby Vision firmware update release window for its 4K display lineup. The update is set to arrive in mid to late January, 2018 and will be available for Ultra HD TVs with the company's X1 Extreme processor, including the flagship A1E OLED Series.

Dolby Vision is a proprietary end-to-end High Dynamic Range (HDR) format that covers content creation and playback through select cinemas, Ultra HD displays, and 4K titles. The process uses expanded brightness to improve contrast between dark and light aspects of an image, bringing out deeper black levels and more realistic details in specular highlights -- like the sun reflecting off of an ocean -- in specially graded Dolby Vision material. Likewise, Dolby Vision also offers a Wide Color Gamut(WCG), providing a greater range of colors than those found in traditional HD sources and TVs using the previous Rec. 709 color standard. In addition, the Dolby Vision process takes advantage of dynamic metadata, allowing it to adjust brightness levels on a scene-by-scene or even frame-by-frame basis to create a more accurate HDR experience than static metadata formats like HDR10.

The Dolby Vision firmware update will start rolling out to compatible Sony 4K Ultra HD TVs in mid to late January in the US. The update will then expand to Europe but it could be toward the end of February before all sets get the upgrade. Here's a rundown of supported Sony displays that are due to receive the Dolby Vision update:
